libvirt-glib: fix introspection and documentation build

Building Gobject introspection during cross-compilation is not an easy task.
Therefore, the meson.build file disables the build for introspection and
also for gtkdoc by default.
This commit adds a patch to enable this, as introspection can be easily built
on newer platforms with yocto/oe.

The options to enable/disable introspection/doc are defined as feature
while the corresponding bbclass defines it as a boolean.
Override this so that it should be possible to be enabled/disabled by using DISTRO_FEATURES.

Inherit  gettext bbclass as used in libvirt-glib.

Add a missing dependency on libxslt.
